I do Fanpages as a hobby/semi-side business-- here is my example page: Apps Examples Page
. On this “Master” Fanpage each tab on the left is a different page for different businesses/topics to give examples of what can be done.
An insurance page example only is at Senior Health Services
. I have mixed results with this page. I am targeting my area, which only has 6000 seniors online with Facebook. So, they are the only ones who will see my ads that I am running on Facebook. If I expand the area, I probability would get more seniors “Liking” the page.
Seniors aren't on Facebook as much as 18-45 yr olds (generally speaking). So if you're selling products targeted to 21-50 yr old group, you may have some very good results using a Fanpage. You can target your ads very specifically with Facebook. Running ads with your Fanpage is very affordable if done correctly.
Also, I noticed most of the Fanpages from most everyone in this tread do not have a reason for a visitor to click the "Like" button. You will notice on the Senior Health Services
site, they have to click "Like" to see the content and get the free information.
So I would say giving something for free is an important factor to have on the Fanpage. Remember that the "Like" button is just the same as an "opt-in" email form. Once the visitor clicks the "Like" you are building a list of people that will become your audience. You can blast your message to them just like an email.
But in Facebook you don't want to just send marketing messages. Facebook is social. Your fans want to interact and don't necessarily want to be sold something. Merging your marketing can be done, but mixed with social interaction.
I can answer general questions if you are thinking about creating a Fanpage or want a custom page built.
